There was a GSD mix who lived about a mile from us, when I'd walk Gunnar we'd see him. Left out 24x7, tethered, had a dog house but no flap on it and no bedding inside. We had a cold snap where it was about zero for a few days, I called animal control about the dog, they checked, he had food, water, and a dog house so there was nothing they could do.
My brother has a husky who is tethered 24x7. He's tried to bring her inside, she doesn't like it. The colder the temps the better too, she loves the cold.
Gunnar likes it when its cold too, he'll go outside for hours when winter hits.
